John is an exceptional gunsmith and exceptional person! Since I've had the pleasure of meeting him, he has done a number of modifications to many of my firearms.
Work John has done so far:
Mossberg 500 - Performed a trigger job that cleaned up the "slop" and break on the trigger and applied Olive Drab Cerakote
Howa M1500 - Applied Olive Drab Cerakote
Yugo M59/66 - Applied FDE Cerakote
Bushmaster XM15 E2S - Applied FDE Cerakote
Saiga AK47 - He converted my Saiga sporter rifle to an Ak configuration and applied FDE Cerakote
